Long-term effectiveness and tolerability of dolutegravir/lamivudine in treatment-naive people with HIV: an analysis of a multicentre cohort at 96 weeks.

Objectives: To evaluate the long-term effectiveness, persistence and tolerability of dolutegravir (DTG)/lamivudine (3TC), compared with the most frequently prescribed first-line treatment regimens, among antiretroviral-naive people with HIV from CoRIS, a multicentre cohort in Spain, in 2018-23.

Methods: We used multivariable regression models to compare viral suppression (VS) (HIV RNA viral load <50 copies/mL), change in CD4 cell counts, persistence and treatment discontinuations due to adverse events (AEs), at 96 (±24) weeks after treatment initiation.

Results: Of 2359 participants, DTG/3TC was prescribed in 472 (20.

Aspergillus spondylodiscitis successfully treated with a long course of isavuconazole.

We present a case of spondylodiscitis caused by Aspergillus fumigatus, which we successfully treated with isavuconazole after voriconazole severe intolerance. Aspergillus spondylodiscitis is a severe and relatively rare form of extra-pulmonary invasive aspergillosis. Typically, voriconazole is the first-choice antifungal drug for treating Aspergillus osteomyelitis or spondylodiscitis.

Ocular infections in international travelers.

Introduction: Ophthalmological conditions in international travelers may be associated with low mortality but high morbidity. Eye involvement in travelers is less frequently reported than febrile, gastrointestinal and respiratory infections, but data probably represent a degree of under-notification.

Methods: an extensive narrative review of the main viral, bacterial, fungal and parasitic infections affecting the eye in travelers was performed.

The Evolving Global Epidemiology of Human Melioidosis: A Narrative Review.

Endemic in over 45 countries globally, recent reports of locally acquired melioidosis in novel geographical areas, such as the Southern US, have highlighted the expanding geographical range of . Climate change and severe weather events have been linked to an increase in cases of melioidosis, which follows environmental exposure to the bacterium. Healthcare professionals should be aware of the possibility of the disease, with its diverse and often delayed presentations, even in areas not previously known to have risk.

Ceftaroline for bloodstream infections caused by methicillin-resistant Staphylococcus aureus: a multicentre retrospective cohort study.

Objectives: To evaluate the effectiveness of ceftaroline vs. vancomycin or daptomycin in the treatment of methicillin-resistant Staphylococcus aureus bloodstream infections (BSIs) (MRSA-BSIs).

Methods: This multicentre retrospective study conducted in 15 Spanish hospitals included data from the first MRSA-BSIs of adult patients between January 2019 and December 2022.

Length of hospital and intensive care unit stay in patients with invasive candidiasis and/or candidemia treated with rezafungin: a pooled analysis of two randomised controlled trials.

Background: Invasive candidiasis/candidemia (IC/C) is associated with a substantial health economic burden driven primarily by prolonged hospital stay. The once-weekly IV echinocandin, rezafungin acetate, has demonstrated non-inferiority to caspofungin in the treatment of IC/C. This paper reports a post hoc pooled exploratory analysis of length of stay (LoS) for hospital and intensive care unit (ICU) stays in two previously published clinical trials (ReSTORE [NCT03667690] and STRIVE [NCT02734862], that compared rezafungin with daily IV caspofungin (stable patients in the caspofungin group who met relevant criteria could step down to fluconazole after 3 days or more).

Bacteriocin distribution patterns in and : bioinformatic analysis using a tailored genomics framework.

Unlabelled: Multidrug-resistant strains represent a major concern due to their ability to thrive in diverse environments and cause life-threatening infections. While antimicrobial resistance and virulence mechanisms have been extensively studied, the contribution of bacteriocins to 's adaptability remains poorly explored. , within the Bacillota phylum, is a prominent bacteriocin producer.

Adaptability of the gut microbiota of the German cockroach Blattella germanica to a periodic antibiotic treatment.

High-throughput sequencing studies have shown that diet or antimicrobial treatments impact animal gut microbiota equilibrium. However, properties related to the gut microbial ecosystem stability, such as resilience, resistance, or functional redundancy, must be better understood. To shed light on these ecological processes, we combined advanced statistical methods with 16 S rRNA gene sequencing, functional prediction, and fitness analyses in the gut microbiota of the cockroach Blattella germanica subject to three periodic pulses of the antibiotic (AB) kanamycin (n=512).

Impact of antibiotics, corticosteroids, and microbiota on immunotherapy efficacy in patients with non-small cell lung cancer.

Lung cancer is a leading cause of morbidity and mortality globally, with its high mortality rate attributed mainly to non-small cell lung cancer (NSCLC). Although immunotherapy with immune checkpoint inhibitors (ICI) has revolutionized its treatment, patient response is highly variable and lacking predictive markers. We conducted a prospective study on 55 patients with NSCLC undergoing ICI therapy to identify predictive markers of both response and immune-related adverse events (IrAEs) in the airway microbiota.

Leishmaniasis in transplant patients: what do we know so far?

Purpose Of Review: The number of cases of visceral leishmaniasis associated with transplant-associated immunosuppression has increased in recent years. Reviewing and updating the latest developments in its diagnostic management, treatment, and follow-up is necessary and relevant.

Recent Findings: Visceral leishmaniasis cases associated with non-HIV immunosuppression are a growing cause of the parasitic infections, and the transplant patients are included in this context.

Selection versus transmission: Quantitative and organismic biology in antibiotic resistance.

We aimed to determine the importance of selection (mostly dependent on the anthropogenic use of antimicrobials) and transmission (mostly dependent on hygiene and sanitation) as drivers of the spread of antibiotic-resistant bacterial populations. The first obstacle to estimating the relative weight of both independent variables is the lack of detailed quantitative data concerning the number of bacterial cells, potentially either pathogenic or harmless, and bacterial species exposed to antimicrobial action in the microbiotas of specific environments. The second obstacle is the difficulty of considering the relative importance of the transmission and selection exerting their combined effects on antibiotic resistance across eco-biological levels.

Should prophylaxis against Pneumocystis jirovecii pneumonia be considered in selected patients with leprosy reactions?

Leprosy reactions often require prolonged high-dose steroids or immunosuppressive drugs, putting patients at risk of Pneumocystis jirovecii pneumonia (PJP). However, no PJP cases are reported, possibly due to dapsone treatment for leprosy. In patients with leprosy reactions not receiving dapsone because of toxicity or resistance and requiring long-term immunosuppression, PJP prophylaxis should be considered.

Plasmid-mediated phenotypic noise leads to transient antibiotic resistance in bacteria.

The rise of antibiotic resistance is a critical public health concern, requiring an understanding of mechanisms that enable bacteria to tolerate antimicrobial agents. Bacteria use diverse strategies, including the amplification of drug-resistance genes. In this paper, we showed that multicopy plasmids, often carrying antibiotic resistance genes in clinical bacteria, can rapidly amplify genes, leading to plasmid-mediated phenotypic noise and transient antibiotic resistance.

Costs and resource utilization patterns in surgical site infections: a pre-COVID-19 perspective from France, Germany, Spain, and the UK.

Background: Surgical site infections (SSIs), mainly caused by Staphylococcus aureus, pose a significant economic burden in Europe, leading to increased hospitalization duration, mortality, and treatment costs, particularly with drug-resistant strains such as meticillin-resistant S. aureus.

Aim: To conduct a case-control study on the economic impact of S.
